Transverse facial clefts are unusual lesions that result from failure of the embryonic mandibular and maxillary processes to properly fuse and form the corners of the mouth.
The incidence of these defects was estimated by Blackfield and Wilde to be about one in 100 of all facial clefts, one in 80 by Ogo and Omori, about one in 300 by Fogh-Andersen, about one in 100 by Park etc. They were more common in males by Gorlin and Pindborg, in females by Ogo and Omori, more common in left side.
This condition of ten is associated with aberrant ear nodules between the corner of mouth and the ear, and sometimes with ear deformities, syndactyly, poly-dactyly, congenital heart anomalies, and rib and vertebral deformities.
Various surgical techniques have been described for their correction, but authors used the Z-plasty. It was very simple and the result was good.
Two cases report and review of the literature will be presented.
